Lonni from Nvidia gave a super quick reply after I shot of a mail to linux-bugs, after filing a report here (turned out to be a dupe of this report, dont know how I missed this one)
There is a post on nvnews tracking the status of this bug, so I tought it relevant to post a link to it here http://www.nvnews.net/vbulletin/showthread.php?t=73033 -- Writing to the gtk textview buffer crashes xorg https://launchpad.net/bugs/49834 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
